Abstract

The invention relates to an integrated floor-heating flexible ceramic tile and a production method thereof. The integrated floor-heating flexible ceramic tile combined by a flexible ceramic layer and a polymer composite electric-heating film is good in flexibility, high in tear resistance, high in elongation at break, high in heat resistance, high in heat efficiency, fast in heating, and the like. The flexible ceramic layer is produced by inorganic powder and polymer materials, and the polymer materials are water-borne epoxy resin emulsion, water-soluble epoxy resin curing agent, rubber elastomer and fluorine-containing polyacrylate elastic emulsion. The polymer composite electric-heating film comprises a polyurethane resin heat-conducting insulating layer, a carbon nanotube polyurethane resin heating layer, a polyurethane resin insulating layer and electrodes. The polymer composite electric-heating film is formed by the heat-conducting insulating layer semi-cured by polyurethane resin, the heating layer semi-cured by carbon nanotube polyurethane resin and the insulating layer semi-cured by polyurethane resin through hot pressing. The soft ceramic layer is integrally connected with the polymer composite electric-heating film through the polyurethane resin heat-conducting insulating layer to form the integrated floor-heating flexible ceramic tile.

Description

technical field [0001] The invention belongs to the field of building decoration materials, and in particular relates to integrated floor heating soft porcelain and a preparation method thereof. [0002] technical background [0003] Flexible facing brick, also known as soft porcelain, is a planar material obtained by processing and molding water-based polymer emulsion and cement as binder, with soil, quartz sand or mineral powder as inorganic filler. Soft porcelain has the advantages of light weight, thin body, good flexibility, rich and colorful appearance, strong expressive force, etc., and it is fast in construction, low in cost, and not easy to fall off.
